Is the widget part of Being Hueman or a plugin that you installed separately?
Depending on that answer, you should ask this question in the forum for the theme which is https://wordpress.org/support/theme/being-hueman or in the forum for the plugin.
Thanks Matt
actually, it’s a plugin I installed separatly, but, before I tried with a simple image, which is a widget part of Being Hueman, and it didn’t work too.
It may be that theme suppresses the widget area in the mobile version. I would try following up using the link I provided earlier.
